Hyperkalemia associated to hepatitis in a peritoneal dialysis patient.

Hyperkalemia is an unusual complication in peritoneal dialysis patients, having a prevalence of around 0.8% among the continuous ambulatory peritoneal dialysis (CAPD) population. The main cause of hyperkalemia in this group is the release of potassium from sources such as gross haematomas and rhabdomyolysis. However, there is no previous report regarding hyperkalemia induced by intracellular potassium shift into the intravascular compartment secondary to drug-induced acute hepatitis in peritoneal dialysis. We present the following case report of a peritoneal dialysis patient, well dialyzed and on a low-potassium diet, who was admitted in our hospital with paralysis secondary to hyperkalemia (serum potassium: 7 mmol/l). Both disorders disappeared using continuous automated peritoneal dialysis (APD) until liver enzymes normalized. We concluded that acute hepatitis can be a cause of hyperkalemia in a properly nourished and well-dialyzed peritoneal dialysis patient.
